How to answer this topic better
A good answer usually works best when you choose one memorable trait and one real example.
Open with who the person is, then add one reason, one moment, and one effect.
You can record an answer, review the transcript, compare it with a stronger sample answer, and retry the same prompt without losing the main idea.
I would like to talk about my older sister because she is the person I admire most. She is a very hardworking and calm person, and she always tries to solve problems without complaining. I admire her because when I was in high school, I had a very stressful period and she helped me stay focused. She used to sit with me, make a simple plan, and encourage me when I felt tired. Because of that, I still see her as a strong role model. She matters to me not only as a family member but also as someone who showed me how to stay patient.
This answer feels around Band 6 because it is clear, relevant, and easy to follow, but the vocabulary and sentence patterns are still fairly simple.
